These glazes are compounded to match porcelain and stoneware bodies. These glazes work well and produce interesting effects when fired in reduction as well as oxidation ( reduction not recommended for HF - 26). We suggest experimentation using Opalescent glazes or High Fire Texturizer in combination with the High Fire Glazes. In liquid form, they are ready to use; dry powdered glazes are mixed in water. HF-26 should be applied thicker than the other glazes in this series. When brushing, 3 coats is recommended. Also we found that these glazes work best at cone 6. All Sahara glazes are leadless.
